Verj^ respectfully, 

S. J. KIEKWOOD, 



The President pro tempore of the Senate. 



Secretary. 



Department of the Interior, 

General Land Office, 
Washington, D. C, January 11, 1882. 

Sir : I have the honor to acknowledge the receipt, by reference from 
the department for report, of a resolution of the IJuited States Senate, 
dated January 6, 1882, calling on the Secretary of the Interior to "fur 
nish the Senate with the report, if any, of the survey of the United 
States and Texas Boundary Commission, made under the provisions </f 
the act of Congress approved June 5, 1858"; and if no final repoi ^ oi' 
said Commission was made, that fact is required to be reported, together 
with the maps, surveys, and report of the work so far as it was. pros- 
ecuted. 

In reply, I have the honor to state that uo report of said survej^ on the 
part of the commissioner for the State of Texas was ever made. 

Several partial reports were made by John H. Clark, Uu/ited States 



2 UNITED STATES AND TEXAS BOUNDARY. 

commissioner, and liis report of September 30, 1861, covers briefly the 
whole field of operations by both commissioners in establishing said 
boundary. 

I transmit herewith, in separate packages, the maps and notes of 
field-work of the survey returned by the United States commissioner ; 
also, the correspondence in the case, including copy of the instructions 
by the department to said commissioner for said survey, and letters to 
the governor of Texas. 

Of the 16 maps returned by the commissioner, Kos. 3 and 16 are miss- 
ing, the latter being a general map of the whole survey, noted on the 
records as "missing " as early as May 7, 1862 ; the former, ISTo. 3, being 
a maj) of that part of the thirty-second parallel from Crow Spring to the 
Pecos River. 

All the maps are in more or less of an unfinished condition as to to- 
pography, lettering, &c., some of them being nearly completed. The 
bound volume, No. 9, contains manuscrii^t notes of all the field-work of 
triangulation and topography. IsTone of the maps or records are authen- 
ticated or approved. 

From an examination of the papers and reports, which will be found 
in the bundle marked "Correspondence," the following is prepared as 
showing, in brief, what was accomplished under said act of Congress 
approved June 5, 1858. (Stat, at Large, Yol. II, p. 310.) 

The Joint Commission on the part of the United States and the State^ 
of Texas commenced work together on the Kio Grande, but the Texas 
commissioner did not remain long in the field on account of personal 
differences between himself and the United States commissioner. A 
new Texas commissioner came and assisted in the survey of a part of 
the west boundary, or one hundred and third meridian, west longitude. 

In the next year, viz, 1860, when the United States commissioner 
surveyed the north and east boundaries, it does not appear from the 
records and papers that the Texas commissioner took any part in the 
work, and the language used by the United States commissioner indi- 
cates that he did the work without any co-operation. 

The east boundary, being that part of the line between Texas and In- 
dian Territory, along the one hundredth meridian, west longitude, had 
been in part previously established by Messrs. Jones and Brown, sur- 
veyors, in 1859, under a contract for marking the boundary-line of cer- 
tain Indian lands, which boundaiy, by treaty of January 22, 1855, was 
the one hundredth meridian, or the line between the State of Texas and 
the Indian country. 

. Said surveyors had marked the one hundredth meridian from the 
north bank of Red River, or what is designated on the United States 
maps as Red River, north to the Canadian River, and about 19 miles 
farther north, and under the instructions issued to the United States 
commissioner by the Secretary of the Interior, for the survey of the 
United States and Texas boundary, he was only required to retrace so 
much of said meridian as had been thus previously established by said 
surveyors Jones and Brown. 

The copy of letter from the department to the governor of Texas,, 
dated August 17, 1858, with the correspondence in the package accom- 
l)aDying this letter, sets forth tbe reasons why the government proposed 
to adopt the survey made by said surveyors as a part of the line be- 
tween the United States and State of Texas. 

As si'jated in my letter dated January 5, 1882, to Hon. S. B. Maxey^ 
the work\of Commissioner Clark was terminated in January, 1862, by 
the directi;ou of the department in letter dated the 16th of that month. 
\ 



UNITED STATES AND TEXAS BOUNDARY; 6 

aud the ofiSce-work was therefore never completed, the fiehl-work hav- 
ing been executed, as required by the Secretary of the Interior, except 
a part of the west boundary, which was not run, viz, from 33° north 
latitude to 33° 45' north latitude. 

No part of said boundary survey has ever been oflicially agreed upon 
or accepted by the two governments as contemplated in the act of Con- 
gress authorizing the survey. 

In explanation of the condition of some of the maps, I have the 
honor to state that they were damaged by water at the tiaie of the Pat- 
ent Office fire in 1877. 

The Senate resolution is herewith returned. 

I am, very respectfully, your obedient servant, 

N. C. McFAELAND, 

Commissioner, 
Hon. S. J. KiRKWOOD, 

Secretary of the Interior.

Camp on Hondo ; remain in camp. 

Down the Hondo to where it turns to E. 
N. E. ; the river again turns to E. S. E. 
and to E. N. S., avoid the long bend by a 
cut-off; avoiding another bend we came to the river again ; 
camp on Hondo ; Capitan W. N. W. 35-40 m. 

Struck the Atasooso, a branch of the Hondo ; struck the head 
of a stream running to E. ; 2-300 yards further came to a 
.stream running from the N. N. W. ; passed it up and crossed 
its source; seemed to be N. N. W. ; traveled J m. N., and 
.saw from a hill our last camp, due south 8-10 m. dist. 

Came to Pecos ; Capitan W. 10° N. 

Came to a vast lagoon of salt water, great canes & rushes up 
the laguna, «fc crossed wiih great labor ; came to river; last 
camp 4J miles in dist. S. 

Along the edge of the mesa, came to the lower end of the 
Bosque Grande ; came to a bed of gypsum, vein 10 feet 
thick ; the river all along winds from side to side through 
a vallev lJ-2 m. wide, decked with mottes of cottonwood 
trees at short intervals. The mesa Rita del Grabriel chaors 
comes in two-thirds of the distance of the Bosque— from 
the lower end on the east bank. 

Along the liver bottom ; the rivt^r makes a big bend here to 
the right about 3 miles. 

Came to the liver again ; Espia N. E. 

Made a detour to descend to river bottom, and came to camp 
on Pecos; Estampedio is 6-7 m. E. S. E. of Efipia, both 
small bills. The mesa San Juan is seen to the right on this 
day's march ; a ravine with fine cottonwood trees is called 
by the guide " Vescera." 

The river comes from the N. N. E. through fine bottoms ; 
came to it opposite a hill called Penas Negras: the river 
bottom narrows here, but just above widens again. 

In 3 m. again we struck the river at a white mound of bluffs 
on the Eio del Toro. 

This river comes from N. N. E. ; struck across & came to it 
again at a rocky point of sandstone ; the river again bends 
off, & in 3 miles we CHme to it at a dry aroyo, with cotton- 
wood trees. This river comes from N. N.W. 

Saw trees on the other side of Pecos through a gap in the 
hills called Latiar. 

Struck the lower end of Bosque redando ; river bottom quite 
narrow, but expands for 4-5 miles till it is 1^-2 m. wide. 

The river in ^ m. leaves the west, & for 3 m. runs along the 
east side of the valley. 

Left the lower bottom and came on the mesa 1,200 yds., 
covered with mesqulte grass, with sand-hill 25-30 f. high 
all along the western border. 

River most crooked & the groupes of cottonwood become 
denser. 

Valley narrower. The Paisar comes in opposite the upper 
half of the mesa just mentioned. 

Traveled over the iiver bottom, composed of fine drift sand,, 
to the upper end of the Bosque redando, and again left the 
river from a hill at the foot of the Bosque, the double head ; 
the last point of "Capitan bore' S. 30° W., and a double 
mound 6-7 m. N. E. of our camp bore N. 

The course here changed to N. W., and we came to camp, to 
our left a small white bluff called El ese. 

3 miles below camp the route was considerable to the west^ 
the river at times lJ-2 miles east; camped in a small valley 
surrounded by bluffs; bottom narrow & enclosed by bluffs. 

Along the river ; ascended the bluff's ; followed a deep trail, 
thinking to avoid a bend in the river, course W. N.W.; after 
3 m. on that trail came to a rocky precipice, which we de- 
scended, & in li m. reached a slough called the "Salado." 

Struck for the riv'er ; 1 m. up a gentfe & 5 m. on a fine plain, 
when we came to deep barrunoas, with difficulty descended 
into it, and came upon a much broken plain of rocks, be- 
vond which was a deep arroyo o^salt water ; the river over 
broken ledges of rock to camp ; river very crooked ; think 
it no more than 8-9 m. to Bosque red. in a straight line. 

Follow the river, which winds very much, but preserves its 
general direction from the N.W ; camped at Beete's rancho. 

Remained in camp. 

Along the Anton Chigo road to N. 

Narrow sandy prairie. 

Over first a stony bluff, then another still higher, and finally 
over a level prairie. 

Decended two rocky precipice, 6-TOO feet h.

LETTERS AND REPORTS OF SURVEYS. 



Department of the Interior, 

July 1, 1858. 

Hon. H. R. EUNNELLS, 

Oov. of Texas, Austin, Texas : 

Sir: I have the honor to enclose herewith a copy of an act in rela- 
tion to the running and marking the boundary lines between the Terri- 
tories of the IT. States and the State of Texas. 

A commissioner will be shortly appointed on the part of the United 
States to carry out the provisions of the act ; and for a speedy and ef- 
fectual prosecution of the survey, it is desirable to commence opera- 
tions at an early day. From information possessed by this department 
it has been thought advisable to commence the survey at the intersec- 
tion of the 32d parallel with the Eio Grande, there having been de- 
termined, by a long course of astronomical observations by various 
parties' connected with the U. S. & Mexican Boundary Survey, several 
points in the vicinity of El Paso dellSTorte, which may serve as a basis 
of observation and measurement, and besides a winter's campaign will 
be more agreeable and prolific of results near the 32nd parallel than on 
the prairies northern borders of Texas. 

I trust that the plan of operations will meet your views, and would 
respectfully request to be informed at an early day if you are in readi- 
ness to co-operate with the United States in carrying out the purposes 
expressed in the act referred to. 

The party on the part of the United States will consist of, exclusive 
of military escort, about 30 or 35 men, including a commissioner who 
will act in the capacity of astronomer and surveyor, an assistant as- 
tronomer, and an assistant survey, or, with their attendants, the neces- 
sary laborers, &c. These officers have had long experience on similar 
works and are familiar with a greater portion of the country adjacent 
to the boundary now to be run and marked. 

The commissioner on the part of the United States will be in San 
Antonio ready to co-operate with such a person as you may select on 
the part of the State of Texas, about the 1st of September next, and a 
copy of his instructions, as soon as they are prepared, will be enclosed 
to you for your information and for that of the person you may select 
to co-operate with him. 

I am, sir, respectfully, your ob't servant, 

J. THOMPSON, 

Secretary. 



264 UNITED STATES AND TEXAS BOUNDARY. 

No. 2. 

Department of the Interior, 

Washington, B. C, July 9, 1858. 
John H. Clark, 

Goni'r, Astronomer, & Surveyor of Texas Boundary, Present : 

Sir : By an act of Congress approved June 5th, 1858, the sum of eighty 
thousand dollars was appropriated to run and raark the boundary line 
between the Territories of the United States and the State of Texas, 
viz : beginning at the point where the one hundredth degree of longi- 
tude west from Greenwich crosses Eed River, and running thence 
north to the point where said one hundredth degree of longitude inter- 
sects the parallel of thirty-six degrees thirty minutes north latitude; 
and thence west with the said parallel of thirty-six degrees and thirty 
minutes north latitude to the point where it intersects the one hundred 
and third degree of longitude west from Greenwich ; and thence south 
with the said one hundred and third degree of longitude to the thirty- 
second parallel of north latitude ; and thence west with the said thirty- 
second degree of north latitude to the Eio Grande. 

As this act seems to contemplate the completion of the field work, it 
is desirable that the organization and outfit be made upon the smallest 
scale consistent with a faithful and proper execution of the work, and 
for this purpose you will proceed with as little delay as possible to San 
Antonio or El Paso, Texas, as it may be most advisable, with your as- 
sistants and instruments, and there prepare to take the field. 

You will proceed first to run and mark that portion of the boundary 
which is defined by the 32d parallel of north latitude, using the mos t 
accurate methods known to science in your determinations. You will 
check the surveyed line by astronomical determinations or by triangu- 
lation or by both methods, when practicable, as often as may,be de- 
manded by the nature of the country. 

As it is impossible, both on account of the expense as well as from the 
desert character of the country to be traversed, for you to obtain more 
than one lunation (and that without corresponding observations) to es- 
tablish the 103d meridian of west longitude, it will be most accurate as 
well as most expeditious for you to transfer the longitude from Frontera 
(a point well established by the United States «& Mexican Boundary Com- 
mission) in fixing that meridian. You will not neglect, however, to ob- 
serve for longitude as near the intersection of the 32d parallel and the 
103d meridian and at other points as circumstances will permit, and keep 
a record of your observations for future use and reference. 

You will erect, in accordance with the 2d section of the act authorizing 
this survey, monuments of earth, stone, or wood, as may be most accessible, 
at the point of beginning; when the line is crossed by roads, rivers, and 
trails; at the corners and as often at other points as necessary to identify 
the line, each monument to be marked with dates and characters desig- 
nating the respective Territories which may be adjacent. 

Should you find it impossible after careful reconnaissance to run and 
mark the 103d meridian from the south on account of the absence of 
water or other physical obstacles upon the Liana Estacado, you may 
cause a careful survey to be made from the intersection of the Pecos 
Eiver with the 32d parallel northward up the valley of that river, thence 
eastward to a poiut on or near the Canadian Eiver, with a view to deter- 
mining this meridian, or to check such observations as you may deem 
necessary to make at this point. As a further check upon this portion 



UNITED STATES AND TEXAS BOUNDARY. 265 

of your work you may, if deemed necessary, and the condition of your 
party and tke resources at your command will admit of it, proceed to 
where the 103d meridian cuts the parallel of 37° north latitude, as deter- 
mined on the survey of the Kansas boundary, and run it southward. 

After surveying^ and marking that portion of the boundary deiiued by 
the parallel of 36° 30' north latitude, and which is known to you to pre- 
sent no obstacles to a rapid survey and demarcation, to j)revent delay 
and expense you will take the lOOth meridian of west longitude as laid 
down on the maj) of the southern boundary of Kansas, or as determined 
and marked upon the surface of the earth by Messrs. Jones & Brown, 
surveyors of the Chickasaw and Choctaw boundaries, from observations 
made by Daniel G.Major, astronomer on the part of the United States, 
at its intersection with the Northern Creek boundary about midway be- 
tween the north fork of the Canadian and the Canadian Eiver, or by 
independent observations, whichever in your judgment from compari- 
son may be found to be the most correct method. 

Having connected with or observed for the 100th meridian at its in- 
tersection with the Creek boundary as determined by the parties above 
mentioned, you will proceed as rapidly as possible over the remaining 
portion of this meridian to Eed Eiver, the termination of your field work, 
making such observations and measurements as you may deem suffi- 
cient to verify it. 

A duplicate copy of these instructions will be sent to the executive 
of Texas for his information and concurrence. If, however, the person 
designated to co-operate with you on the part of the State of Texas 
should receive instructions from the proper authority confiicting ma- 
terially with the plan of operations herein specified, or should he pro- 
pose a different course to be pursued, you will confer freely with him, and 
adopt such plan as may be mutually agreed upon, provided it does not 
conflict, in your judgment, with the interests of the United States, and 
communicate the same to this department for its approval. 

As it is indispensable that each government should be furnished with 
a full and accurate record of the joint proceedings of the commission, 
they will doubtless instruct their respective officers to keep such record 
in duplicate. You will therefore keep a faithful record of this character 
of all your proceedings. 

As soon as the boundary shall have been ascertained and marked you 
will cause a true and accurate map to be made of the country through 
which it passes in its extent, embracing as much topography of the ad- 
jacent couiitry as is possible to obtain, and a duplicate copy of said map 
certified by the respective commissioners, together with a copy of the 
field notes, will accompany the records of the proceedings. 

Further instructions in regard to the economy and organization of 
your party will be shortly given you. 

I am, sir, respectfully, your ob't servant, 

J. THOMPSON, 

Secretary.

SiE : The very great interest manifested by many of our citizens in

No. 4. 

Executive Office, 
Austin, 28th July, 1858. 

SiE : I have the honor to acknowledge the receipt of yours bearing 
date July 9th, containing copies of instructions to John H. Clark, com- 
missioner, &c., to run and mark the boundary line between the terri- 
tories of the United States and the State of Texas. 

You are pleased to request to be informed at an early day of the con- 
ijurrence or non-concurrence in the views expressed, and to solicit any 
suggestions I may deem proper to make, which I shall now proceed to 
offer. The place of beginning or initial point of the survey, as designated 
in your instructions, is not without serious grounds of oljjection to the 
State of Texas, because of the large interests of a portion of her citizens 
in that portion of our territory lying immediately north of Eed River, 
along and adjacent to the supposed boundary line. The immediate, if 
not chief object of the State of Texas in urging an arrangement with the 
U. S. Gov't for the early definition of the boundary has been to remove 
the doubts and uncertainty from the minds of those of her citizens who 
have invested their rights in that portion of the territory, the title to 
whose lands must remain suspended in uncertainty until the line has 
been properly defined and marked by the two governments. 

You will perceive from these facts the serious inconvenience, and per- 
haps loss, that will result from delay in defining that portion of the line 
north of Eed River at the earliest possible time, and of establishing the 
initial point or place of beginning on the Rio Grande in accordance with 
your instructions to the U. S. commissioner. 

It is plain that persistence in your instructions on this head would 
not only disappoint the wishes of those directly interested in the settle- 
ment of the question, but the just and reasonable expectatioii that the 
convenience of Texas would be consulted in taking the necessary steps pre- 
liminary to its fi^nal adjustment, as it can be of little importance to the 
gen'l government where operations shall commence, and of so much to 
Texas. I must, as her representative in the premises, be permitted to 
insist on such modification of the instructions, in regard to the point of 
beginning, as Avill conform to her known interest. I discover no other 
^•rounds of objection to the instructions, except as to the precise time of 
taking the field, which, however, I presume will be adjusted at the con- 
venience of the commissions when fully organized. That of Texas will 
be organized in a few days, of which you will be notified, with such ad- 
ditional suggestions, if any, as may be deemed important in behalf of 
this State. 

I am, sir, respectfully, your ob't serv't, 

H. R. RUNNELS.

UNITED STATES AND TEXAS BOUNDARY. 267 

No. 5. 

Department of the Interior, 

Washington, August nth, 1858. 
Hon. H. II. Runnels, 

Governor of Texas : 

Sir : I have the honor to acknowledge the receipt of your communi- 
cation of the 28th ultimo acknowledging the receipt of mine of the 9th 
ultimo, enclosing copies of instructions to John H. Clark, esq., commis- 
sioner, &c., on the part of the United States to run and mark the boun- 
dary lines between the territories of the United States and the State 
of Texas. 

I regret that the proposition of this department in reference to the 
starting point does not meet with your approval, and I respectfully beg 
leave to present for your consideration some of the leading reasons 
which induced me to propose commencing on the Rio Grande in pref- 
erence to the Red River. It was doubtless the intention of Congress 
in authorizing this survey to have the entire lines described in the act 
accurately determined and marked upon the face of the earth, and a 
specific appropriation was made to effect this object. In considering 
this subject with a view to devising a plan of operation which should 
best subserve the interests of the general government and that of the 
State of Texas, I was fully aware of the great interests of a portion of 
the citizens of that State in the establishment of the true boundary 
north of Red River. 

The boundaries now to be run are astronomical lines, requiring for 
their establishment the most delicate and accurate observations of the 
lieavenly bodies; and for the purpose of making these observations, 
several months of apparent inactivity will be required before the par- 
ties can commence the determination of the lines from the initial points. 
To insure an accurate determination of any given initial, it is usual to 
have corresponding obsei'vations taken at some one of the old estab- 
lished observatories in this country or Europe, "the results computed and 
sent to parties in the field to enable them to apply the proper correction 
due to the difference between the true position of the object observed 
and its position as given in the nautical almanacks. To exchange obser- 
vations of this character will require several months, and if no such 
corresponding observations are made, the probable error in a given line 
of longitude fixed by observations in the field alone will be about three 
miles. 

By commencing on the Rio Grande, therefore, you will readily per- 
ceive that a saving of at least six months of time will be effected (which 
will be equivalent to at least |20,000 to the United States, and doubt- 
less as much to Texas.) The position of Frontera has been determined 
by the United States & Mexican Boundary Commission, by combined 
observations upon the moon at San Elciario and Frontera, running 
through a period of seven months, and corrections deduced from cor- 
responding observations made at Cambridge, Mass., and Greenwich, 
England, have been applied to these results, giving for Frontera, adja- 
cent to the 32d parallel, the most accurate position in longitude yet 
determined in the interior of the continent. I therefore consider com- 
mencing at the Rio Grande paramount to every other consideration, in 
the view of the extent of the lines, and the importance to both govern- 
ments of accuracy in their determination. 

Another reason which induced me to propose commencing on the Rio 
Grande is the economy with which these operations can be carried on; a 



268 UNITED STATES AND TEXAS BOUNDARY. 

less number of wagons, mules, and men will be required, from the fact 
that supplies can readily be drawn from the Eio Grande from Fort 
Davis and Fort Chadbourne. The parties can be supplied from either of 
these sources while operating between the Rio Grande and the 103d 
meridian ; and after the completion of this portion of their work can be 
reinforced from the same sources with sufficient provisions to enable them 
to reach the vicinity of the parallel of 36° 30', and from this point they 
can easily draw supplies from Anton Chico, on the Pecos, or from Fort 
Union, to enable them to complete their operations in this region, and 
from thence along the parallel of 36° 30' and the 100th meridian to Eed 
River. 

There are several o^her reasons, no less cogent, why it is best, in my 
opinion, to commence on the Rio Grande, viz, the 32cl parallel is more 
accessible than the 100th meridian,for the reason that the greater part of 
an outfit can be procured on the Rio Grande, and be put immediately on 
the line. The climate of winter is milder, forage and grazing for the 
animals are more accessible and certain. 

The principal objections to commencing on Red River are, first, that 
it will involve a serious delay in fixing the initial point of the 100th 
meridian, requiring, as I have before stated, several months' careful as- 
tronomical observations and an exchange of observations with some 
fixed observatory. And, besides, by the time the commissions of the 
respective governments are prepared to commence their labors at that 
point, that line will probably have been determined and marked by the 
U. S. surveyors, Messrs. Jones and Brown, who are now engaged upon 
the surveys of certain boundaries in the Choctaw and Chickasaw country, 
under the provisions of the treaty of Jan'y 22, 1855. Of the iDurpose 
of the United States to cause the 100th meridian, as far north as about 
the parallel of 36° 20', to be determined and marked, I informed you on 
the 11th of January last, requesting you to take such steps as you 
deemed proper for the interest of Texas. The above-named survey ors^ 
are provided with a competent astronomer and excellent instruments,, 
and their line will probably require but simple verification on the part 
of the joint commission ; and for all purposes appertaining to the in- 
terests of the citizens of Texas along and adjacent to the proposed 
boundary line north of Red River, Brown and Jones' survey must prove 
sufficient and satisfactory. If they vary from the true line at all, that 
variation must prove to be inconsiderable, and in no way detrimental 
to the interests of Texas, for, so far as fixedness and certainty are con- 
cerned, there can be no locations of land, no perfection of titles, until the 
surveys are officially agreed upon and accepted by both governments. 
There will, therefore, be no possibility of a "serious inconvenience" or 
loss arising from delay in defining this portion of the boundary. This 
line, being established in the manner described, will reduce the labors 
of the joint commission by more than 100 miles, with a saving of from 
$8,000 to 110,000. 

Another objection to commencing on Red River is the large amount 
of transportation which will be required to transport provisions, &c., 
for several months' stay in camp, for making observations, and to sub- 
sist the parties in their progress as far as the intersection of the parallel 
of 36° 30' with the 103d meridian of longitude, a point accessible from 
Fort Union or Anton Chico. And, again, were the parties to commence 
on Red River by the 1st of October they would reach the vicinity of the 
parallel of 36° 30' in midwinter, and be subjected to the rigors of the 
climate in a region well known to be barren and desolate in the ex- 
treme, with little grass for the subsistence of their animals (for the 



UNITED STATES AND TEXAS BOUNDARY. 269 

transportation of a sufficiency of corn would be almost impossible), with 
water of a gypseous and deleterious character, and with little fuel. In 
the ojiinion of this department, based on the opinions of some of its offi- 
■cers, who are well acquainted with the character of the country north 
of the Canadian Eiver, a surveying campaign in that region in winter 
would be hazardous in the extreme, if not impossible. 

I hare briefly stated the principal reasons which prompted me to pro- 
pose commencing operations on the Rio Grande in the coming autumn. 
It is of very little consequence to the United States, in itself, as to which 
portion of the boundaries be first run, and I conceive it to be of as little 
consequence to Texas in that respect, since the 100th meridian will 
doubtless have been run and marked before our parties take the field. 
But, in point of economy and accuracy, I conceive it to be of the great- 
est importance to both parties interested. By commencing at the Eio 
Orande the saving in transportation will be about $20,000, and the 
saving in time, say six months, will be about $20,000 more, making an 
aggregate of $40,000 saving to the United States, and there will be, of 
•course, a proportionate saving to the treasury of Texas. 

In the above views I do not wish to be considered as persisting in the 
course proposed in the instructions sent you on the 9th ult. I am act- 
uated by no other motive than a desire to accomplish the object author- 
ized by the act of Congress in the most accurate, rapid, and economical 
manner ; and I indulge the hope that upon a careful reconsideration of the 
case in all its bearings you will be prepared to adopt my views in regard 
to the starting point. 

The commissioner on the part of the United States will be provided 
with complete duplicate sets of surveying instruments, one of which 
your commissioner is at liberty to use, and a complete set of astronom- 
ical instruments, which may be used by both parties to advantage. 

In order to economize time and to have a more perfect understand- 
ing, this communication I have entrusted to Mr. Clark, commissioner, 
&c., on the part of the U„ S., to place in your hands. Mr. Clark will be 
able to elucidate more fully the views herein expressed. 
I am, sir, respectfully, vr. obt. servant, 

J. THOMPSON, 

Secretary.

San Antonio, Texas, Sept. 8th, 1858. 
Hon. Jacob Thompson, 

Secretary of Interior : 

Sir: By letter of the 4th inst. from Austin I informed you of my pur- 
pose of coming to San Antonio to consult the com'r. I took the oppor- 
tunity which presented itself of accompanying Governor Eunnels, so 
as to 'il^>Ye both him & the commissioner a party to any arrangement 
agreed upon. They have concluded to adopt our plan of operations 
throughout, and I have fixed on some time during the 1st week of Nov. 
for leaving San Antohio. 

The mules and wagons are already bargained for, and I will have an 
ambulance and wagon at Indianola about the 15th October to transport 
the assistants & instruments to this point. This is ample time, if they 
leave Washington immediately on the receipt of this letter. 

It will require about fifteen thousand (15,000) dollars to make the 
outfit, and I request that this amount, exclusive of what may be neces- 



270 UNITED STATES AND TEXAS BOUND AEY. 

sary to pay for the instruments & the placing of the assistants in the- 
field, be put to my credit at New Orleans. 

I beg leave to call your attention to my letter of Aug. 5th to you, 
asking for an escort, an order to sell me arms & tents at this place, 
& subsistence at the various posts along our line of march & survey. 
The escort can be dispensed with till w^ commence work, though an 
attack & loss of mules is to be apx3rehended between here and El 
Paso. I shall have but little difficulty in securing an outfit of wagons. 
and mules. The cost will, however, be rather heavy. The item of corn 
was not estimated for, which, in consequence of taking the field at this 
season, will be very considerable. 

In addition to the appointments of Messrs. Weyss, Campbell, & Emory 
I request that Jas, McLeod, of Georgetown, D. 0., be appointed asst. 
at a rate of pay not exceeding |50 per month, & one ration per day. 
He is the only one of the three young you referred to me that I believe 
will be of service. 

I have the honor to be, respectfully, yr. obt. ser'nt,

Hon. Jacob Thompson, 

Secretary of Interior : 

Sir : I have to report that we discovered water near the corner, the 
intersection of the 32d parallel & the 103d meridian, & will proceed at 
once to finish the 32d parallel & run the line to the northward more than 
half way through the centre of the Llano, which will easily enable us to 
connect it, from the other side 5 if, then, no other available water be 
found, I shall carry out that part of my instructions which direct me up 
the Pecos, & take up the line on the Canadian or at the intersection of 
the 103d meridian & the parallel of 36° 30'. 

The main body of the escort & of my camp remains on the Pecos 5 if 
the " overland mail route" is not changed along this portion of it, which

is contemplated, before my return, I will then send in a map & notes of 
the boundary not heretofore reported. It is impossible for me to indicate 
to the department any other point of communication with me hereafter 
than Fort Union ; and I hope it will not be necessary for me to depart 
even that far from the line. 

I have further to report tha.t the Texas com'r informs me (a copy of 
his letter is inclosed marked A ) of the withdrawal o* his party from 
the field. As an answer for the reason of his course there assigned, I 
inclose copies of two letters, marked B, that passed between Mr. Mills, 
surveyor pro tem. on the part of Texas, & Mr. Weyss. After the diffi- 
culty between Mr. Mills & Mr. Weyss, Mr. Scurry, the Texas com'r, 
came out to this camp on a mail-coach, & put this question to me in writ- 
ing : Whether it was my intention to discontinue the survey as agreed upon ? 
The only agreement on this point will be found in the journal of pro- 
ceedings Jan. 3d, '59, where we state that the survey shall be in " con- 
junction," & declare that separate surveys are unnecessary ; now the 
surveying was actually done in this manner : Mr. Weyss did all the 
work, & Mr. Mills looked on, »& took a copy of his notes. I answered 
the above question ; but it being considered evasive, I replied the sec- 
ond time as follows: "It has not been & is not now my intentioa to dis- 
continue the joint survey as agreed upon between us in any particular. 
I am free to say, however, that I regard it as impossible for Mr. Mills 
& Mr. Weyss to act together efficiently in the manner pursued hereto- 
fore, since the difficulty between them at the last monument which you 
have pleased to treat as partly official & partly personal. I will, if you 
wish, upon your requisition & receipt, turn over to you such instruments 
as may be necessary with the view of having each party do its own sur- 
veying, or I will receive & duly consider any propositions you may think 
proper to make." To this Mr. Scurry made no response except what is 
contained in the letter inclosed, marked A, & already referred to. 

I deem it unnecessary to annoy the Secretary with a complete history 
of this affair, confining myself to the single point, or pretext as it really 
is, which Mr. Scurry has tried to make against me in order to cover his 
own negligence & indifference to the survey. If complaints are made, 
I hope the Secretary will do me the justice to give me a personal hear- 
ing before he makes a decision. I can show that Mr. Scurry was 
never near the works, except on two occasions, when he was forced out 
of El Paso by the disorganized state of his party ; that he engaged in 
private business at El Paso to the neglect of business that it was his 
duty to perform with me 5 that I had to give his surveyor transporta- 
tion at the expense of my work on the line ; that our party has done 
almost the whole of the work ; that his surveyor resigned because he 
(Mr. Scurry, the com'r) neglected to supply his party with rations; 
that he appointed a Mr. Mills pro tem. who ignored me as chief of the 
party & who was entirely deficient as to the duties of his position ; & 
that" when it was clear Mr. Mills & Mr. Weyss could not get along 
together to any purpose, he sought it as an excuse for withdrawing his 
party (as he had previously himself) from the commission, instead of 
responding to my offer to have each party do its own surveying, which 
was the proper course for a joint survey to pursue, or else what was the 
object of two parties being in the field ? 

The difficulty between Mr. Weyss and Mr. Mills was merely a per- 
sonal quarrel, & it is simply a ridiculous view in Mr. Scurry to make 
it a pretext for withdrawing his party from the field. I believe the real 
reason for Mr. Scurry's abandonment of the field will be found in the 
fact that he came out with the view of locating land ; but not being 



272 UNITED STATES AND TEXAS BOUNDARY. 

able to make a fortune out of it, as lie expected and frequently expressed 
he lias no longer any object to continue on the line. 
I remain, respectfully, y'r ob't servant, 

JOHN H. CLAEK, 

U. 8. Coin'r, dc, lex's Bdr. Survey. 



A. 



In Camp on Pecos, May 11th, 1859. 
SiE, : Your declaration, made verbally to me on yesterday, that Mr. 
Weyss, the U. S. surveyor, tvould not continue the survey of the Texas 
boundary conjointly, as heretofore, with the Texas surveyor, renders a 
compliance with the terms of the agreement between us as the repre- 
sentatives of our respective governments impossible; that agreement 
is, therefore, terminated by the act of the U. S. surveyor in refusing to 
comply with the terms of an exj)ress agreement entered into by the U. 
S. commissioner. Without commenting upon the singularity of a sub- 
ordinate officer of your commission assuming to violate an agreement 
made by his chief, I shall content myself with a protest against such 
violation, as that agreement was one of the conditions upon which Texas 
consented to commence on the Rio Grande. 

It only remains for me to announce to you officially that, under the 
circumstances, the Texas commission will not proceed with the survey 
from this point. 

I am, very respectfully, your ob't serv't, 

WM. E. SCURVY, 

Texas Coin'r. 
John H. Clark, Esq., 

Com'r, (&G., cfcc, Tex. B'Wg Survey. \ 



B. 

Camp on the Pecos, May 8th, 1859. 
Mr. John E. Weyss : 

Sir : I demand that you state to me in writing whether you did not 
make the following statement, in substance, to me at our last interview 
on the plains : 

" I refuse to continue the survey any farther with you. My commis- 
sioner, John H. Clark, has instructed me to have nothing further to do 
with you; address yourself to him. The reason of my breaking my 
promise to see you and let you know my propositions for further opera- 
tions on my arrival in Mr. Clark's camp was his direction to me not to 
cross the river to see you and his refusal on my request to do so himself." 
Yours, &c., 

Al!TSOiT MILLS. 



Camp on the Pecos, May 9, 1859. 
Sir: To your note of yesterday I make the following reply: I would 
have taken"^little notice of your imperative "demand" at all, if not Mr. 



UNITED STATES AND TEXAS BOUNDARY. 273 

U. S. Ooraniissioner Clark's name appeared in the note, and, as he is 
closely connected with the index of it, I owe it, therefore, to him to give 
a full statement of what has happened between us. 

Yon seem to he endowed with a great faculty to misconceive, misap- 
prehend, and misunderstand everything. You take expressions which 
I have used in conversation at different times under different circum- 
stances, garble them together, make one long speech out of it, and 
tiually condence it to a thing which you are pleased to term the ^^sub- 
stmice" of a late interview, and then having the thing fitted to your 
purposes "demand" a written statement (you mean, perhaps, yes or no) 
to that prepared "substance." That won't do. 

As much as I can gather from your somewhat confused letter, it ap- 
pears to me that it contains the charges that 1 1st made a formal promise 
to you to come over the river and acquaint you with certain propositions 
concerning the survey. 

2d. That to excuse my breach of promise I stated to you that by order 
of the Com'r Clark I failed to do it. 

3d. That my final determination not to have longer any personal con- 
nection with you was also created by Mr. Clark's direction or order. 

To this confusion of things you "demand" me to make a statement. 
It seems to me that in a very few days you have entirely forgotten in 
what connection the incidents happened by which that rupture between 
us was produced, the circumstances under w^hich I used somewhat sim- 
ilar expressions, as you make me do in our "last interview," and which, 
brought in proper connection with time and incidents, will sound and 
appear quite different from those in your "substance." 

In the first place, I had never a really official connection with you. 
I informed you when you came first to see me for the purpose of making 
arrangements concerning the survey that I had neither power nor au- 
thority to enter into agreements of that kind with you, and that the U. 
S. commissioner, J. H. Clark, was the proper person with whom you 
had or could make such arrangements; my duty and occupation being 
only to assist Mr. Clark in the running of the boundary line, execute 
his orders, and act under his instructions. You refused positively to 
treat with Mr. Clark, declaring that you had nothing to do with him 
and would have nothing to do with him. At your request, as you de- 
clared not to be willing to speak to Mr. Clark, at your request, I went 
finally to him to ask in your name about his opinion and instructions 
for the further joint proceedings of the survey. Mr. Clark's answer 
was verbal, that he had no objection whatever to your going along with 
me, if I could agree with you, but that, as far as myself was concerned, 
he expected that, under all circumstances, I had to carry on the survey 
according to his instructions and orders. So we became connected, 
personally only, and for as long as we could agree, because Mr. Clark 
by consenting to your going along with me did not authorize me to 
make arrangements and treaties with you which might, i^erhaps, have 
I been adversely to his views, and if you had anything to propose it was 
i always necessary to subject it to Mr. Clark's approbation and consent 
before I could have agreed to it. In this way we only were connected. 
(And now to your charges and assertions. When I had reached the last 
jflag, 30 miles east of Fecos, I declared it time to make a reconnoissance 
to the east to inspect the corner and find out how possible it would be 
to carry out the survey to it. I pro|30sed the scout; you wanted to ac- 
company me, and I, of course, had no objections to it. I run the line 
with the compass as far as the corner, and then we began our search 
for water, in which we were unsuccessful. After having reconnoitered 
S. Ex. 70 18 



274 UNITED STATES AND TEXAS BOUND AEY. 

tlie whole Hue aud finding no water on or near the corner, I exjDressed 
my opinion that I considered it exceedingly difficult, if not impossible, 
at all to reach the corner by triangulation. 

Then you asked me what I proposed to do. I told you my plau to 
run the remainder of the line by compass, sextant, &c., but declared at 
once to you that, so far, this only was a plan of my own ; that my in- 
structions from the U. S. commissioner required me to run the line out 
by triangulation, aud that as I found that modus operandi impossible I 
could not on my own responsibility substitute anything else for it ; that 
I only could report the state of things to the commissioner and submit 
anew plan ; in fact, that I could not do anything before 1 had reported to 
the commissioner and received new instructions. You admitted all that 
as proper and true. In coming to our depot camp you prepared to start 
for the river, and I, having no animal to ride, began to make a report in 
writing to the commissioner, of ivhich you are iv ell aware, because you 
not only saw me tvrite, hut I heg'd you, as I did not intend to go myself to 
the river, to take my letter along to the commissioner, tchich you consented 
to do. 

It appears clearly from those facts that I did not intend at all to go 
to the river; that youkuew it (as you consented to carry my letter), and 
that therefore I never could have contemplated or made to you the 
"promise" to come over the river to see you, &c. It seems that your 
mistake concerning that "promise" arose from the following remark 
which I made in the course of our conversation after we arrived in camp. 
I remarked that "if I had a riding-animal I would go myself to Mr, 
Clark's camp, as such sort of business is much easier settled by a verbal 
report than by long letters;" to which you answered me in these very 
w^ords ; " 1 wish to God you icould come in yourself; you hioic I donH want 
to speaJc to Mr. ClarTi and he does ivant to speaJi to me, and if you donH 
come in Iivill not hnoic amjtMng,^^ &c. To this I replied, Oh ! well, you icill 
hear it in some way or other. 

How out of these facts you can make a promise on my part to come 
over the river to see you, &c., I can scarcely see, and if you really be- 
lieved so, then you have been laboring under a strange mistake. The 
first point I hope is settled. 

2d. Not having quite finished my letter to Com'r Clark when you left, 
and having no other opportunity (the men, as you know, having all been 
sent away). I was obliged to wait until next morning, and then the only 
opportunity was the water-wagon. Then I determined to go in myself, 
settle the business, and return with the next outgoing wagon to my 
camp. I reached Mr. Clark's camp at 1 J p. m. I reported to Mr. Clark 
what I had seen aud what I proposed for the future continuation of the 
survey. Mr. Clark,. after hearing my statement, concluded to go out him- 
self, see about the matter, &c., and reserved his final decision, on new in- 
structions to me, till he would have examined the unfinished part of the 
line himself. 

These facts again show that even if I had given you a promise (which 
I have already proved I never did) to report or make known to you the 
further intended operations, I had at that time nothing to communicate 
to you, Mr. Clark reserving his opinion and further instructions till he 
had examined the line himself. The proposed trip of Mr. Clark to the 
corner was entirely a private concern of his own. I mentioned that you 
very likely expected to be invited to this trip. N^obody seemed inclined 
to invite you or request your company, and, seeing this feeling, I natur- 
ally dropped the matter, leaving it to the commissioner, who went out 
on the scoutj to invite you or not, as he thought proper, and I had no 



UNITED STATES AND TEXAS BOUNDARY. 275 

longer anytUiug to do with it. He found it proper not to invite you. 
How Ccan ja^u attach bhime to me for the neglect ? 

How, after having so often declared that you wanted to have nothing 

to do with Mr. Clark, how could you expect that he would invite you, 

or did you report or invite Mr. Clark or me when you went out on your 

' scouts'? Whatever may be the case, 1 had nothing to do with it. The 

excursion was the commissioner's and it rested with him to invite or not 

to invite the persons he saw proper, and no offence toward you was or 

could have been intended by me if you were left behind. I left Mr. Clark's 

camp after about half hour's stay, and returned to my own in the night. 

' Before I left, Mr. Clark charged me to erect a monument opposite the 

; depot camp, and as soon as it was done to send the men and animals 

to the river, as they were not longer wanted out there at present. I had 

early next morning, according to Mr. Clark's instructions, the monument 

' erected and men and animals sent in. The monument was scarcely tin- 

I ished when you appeared, and the first I heard, you still sitting on your 

I mule, were the following expressions : 

" God damn you, sir; you area Goddamned liar; you are a damned Dutch- 
man; you never teas nor is a gentleman ; you God damned foreigner,'''' &c., 
and more such civil and courteous expressions j at the same time and 
with the same language orderiug me to pull down at once the monu- 
ment, it being erected without your permission (meaning the monu- 
ment which I had erected in the morning by and under orders of the 
U. S. commissioner). Scarcely was I able to find out betv^een your 
cursing what was tlie real reason of your strange behaviour, and learn- 
ing finally that the only cause was your not having been invited to Mr. 
Clark's scout, I repudiated any intentional offence by declaring that I 
had charged the other gentlemen to invite you if they found you, and 
if they failed 1 had nothing to do with it. To this you asked, ^'■Well, 
then, tvhy did they fail ? " and then by this time, under your continued blas- 
pheming, necessarily excited, then I answered you, " Because they donH 
want to have anything to do with you, neither tvill I have longer anything 
to do with you.''^ After having cooled down a little you came forward 
with a written agreement, asking my signature to it. Without entering 
into the merits of your proposed agreement now, I can only here again 
express my astonishment how, after such a scene, having abused and 
cursed me without any cause in the grossest manner possible ; how, after 
all that, you can come forward and invoke my aid and assistance to help 
you to carry along the survey. 

Then I declared that after what had happened I could not have longer 
any personal connection with you, and that from that moment I refused all 
I further connection with you, and told you that if you had to make any fur- 
I ther communications concerning the survey you must address yourself in 
I future to Mr. J. H. ClarTt, JJ. 8. corner, chief surveyor, &c. 
j After that, you again asked me if I had not told you formerly that 
I Mr. Clark had left the matter (our working together) to me. I repeated 
I what I have already mentioned in the beginning of this statement con- 
i cerning our connection. 

\ Even after this reiterated declaration on my side, you insisted to have 
I my signature to your proposal either consenting or stating my objections. 
I finally, to end the whole disagreeable scene, I put the following words, 
I believe, under it : " Sir, I have to make with you no arrangements con- 
cerning the survey of the boundary line ; if you have to make any com- 
munications of that kind, address yourself to the U. S. oom'r, J. H. Clark." 
; This is not only the "substance" but the full statement of the whole 
\ disagreeable alfair. You will find in it nearly all the same exj^ressions 



276 UNITED STATES AND TEXAS BOUND AKY. 

which you give in your "substance" of our last interview, only in quite 
different connection, not as you please to file them together, but as they 
really happened. 

You have insulted me in the grossest possible manner without any cause 
whatever. This statement of the facts shows clearly that you had no 
reason to any complaint whatever against me, but you misunderstood or 
misconstructed everything which happened. That, coming out to camp, 
instead of asking an explanation if you felt yourself injured or wronged, 
you used at once such language toward me which you knew very well I 
would any further a connected work between us make a matter of im- 
possibility. Your behaviour was not of a man who feels himself badly 
treated or injured, but it was that of a man who wanted to raise a quar- 
rel by all means. This is my impression. You had no reason to treat 
me as you did, if it was really you will to carry on the survey with me 
together. But I believe that you wanted to split the concern for some ' 
reason or other, and wanted some pretext for it. However, this is only 
my private opinion. 

You know very well that the origin of the differences in the two com- 
missions is not with me. I was far away when the first bad feeling was 
created. I have nothing to do with your quarrels, official correspond- 
ences, statements, &c. I want to have done with this, and in future : 
nothing to do again, and now two questions to you and I have done? 
Ist. Why, after having so repeatedly informed you that not myself but 
Mr. J. H. Clark is the com'r, chief astron'r, & surveyor, that he is the only 
person with whom you can make treaties and arrangements, why do you 
all the time insist on only communicating with me and ignore him ? 2d. 
Why, after insulting me in the manner you did, damning and cursing 
me, why do you still insist to survey with me together if you are able^ 
to do it alone? Why don't you take your instrument, run and fix the 
line, and finally compare the result with the work of the U. S. commis-> 
sion? This is the only proper way to do it; all that what you proposed, 
to me did not amount to anything. 

I hope that here our correspondence will end, I having neither time 
nor inclination to continue it. I have finally to inform you that as 
well in your letter as in mine the name of Mr. Com'r Clark so often ap' 
pears, I found it proper to furnish to him a copy of your letter and my 
answer to it. ■

Sir: I avail myself of the opportunity presented by Lt. Lazelle, 
com ding escort, to make a brief report. I have just returned to the 
Pecos from the establishment of the corner & the tracing of the 103d 
meridian, about 40 miles. I inclose a copy of observations made near 
the corner, & a sketch, which, with those already sent in, show the 
determination and tracing of the line as far as completed, a distance 
of about 250 miles. As soon as the escort communicates with Fort BlissJ

Camp in the Creek Nation, 

Near North Forlc Totv7i, Oct. 27, 1859. 
Hon. Jacob Thompson, 

Secretary of Interior : 

Sir : I arrived at Eabbit Ear Creek from Ft. Union the 3d of August, 
and j)roceeded at once to establish the northwest corner of the boundary, 
which was done by transfer from the Kansas line as to longitude, the 
result of independent observations being used for the latitude. A luna- 
tion was also observed with the view of serving as a check on the accu- 
racy of the transfer. 

After the establishment and marking of the corner, the 103d meridian 
was taken up and surveyed across the Canadian and to a point on the 
Llano Estacado south of the 34th parallel, a distance with the survey 
from the Kansas boundary of about 210 miles. Having thus traced the 
line as far out on the staked plain as I believe there is any practical 
necessity for in connection with what was done from the south, I was 
compelled from the lateness of the season to suspend further operations 
and come into winter quarters. 

Had I not been forced to quit the line on the south from physical 
causes, come up the Pecos, and then travel 600 miles for winter quarters, 
I could easily have completed the survey of all that part of the boundary 
covered by my instructions this season, despite the many moral obsta- 
cles against which I had to contend at every step. This fact is made 
evident from the statement of the work done and inclosed herein, show- 



UNITED STATES AND TEXAS BOUNDARY.

ing more than 3,000 astronomical observations and. the snrvey of about 
850 miles, 450 of which is a triangulation on the line proper. The amount 
and quality of this work will compare most favorably with what is & has 
been done on similar surveys. 

I shall, on arriving" near Ft. Smith, reduce the commission, and thus 
cut off all unnecessary expenses ', and then there will be enough of the 
appropriation left to run the small part of the boundary yet unfinished. 
As soon as this reduction is accomplished and the property safely dis- 
posed of I will go to Washington for the purpose of reporting in person 
the affairs of the commission. 

I am, sir, respectfully, your ob'd't serv't,

Department of the Interior, 

Washington, D. C, March 19, 1860. 
Hon. Sam Houston, 

Governor of Texas, Austin, Texas: 
Sir : I have the honor to inform you that the commissioner on the part 
of the United States, under the act of June 5, 1858, for running and 
marking the boundary lines between the Territories of the United States 
and the State of Texas, will resume operations this spring, and expects 
to leave Fort Arbuckle on or about the 10th of May next, and I would 
respectfully suggest that the commissioner on the part of Texas be 
directed to proceed to that place for co-operation at the time above spec- 
ified. 

I am, sir, respectfully, your ob'd't servant, 

J. THOMPSON^, 

Secretary.

Executive Department, 

Austin, April 16, 1860. 
Hon. Jacob Thompson, 

Secretary of hiterior : 
Sir : Your letter dated March 19 has just come to hand. 
It having been delayed on the route from here to Washinoton, it will 
be impossible for the Texas commission to reach Fort Arbuckle by the 
time proposed. Every endeavor will be used to hasten its departure, 
and I trust no serious delay will occur. 

I have the honor to be, very respectfully, yours, 

' SAM HOUSTON.

Santa Fe T^ail, N. M., July 16, 1860. 
lion. Jacob Thompson, 

Secretary of the Interior : 

SiH : I have finished the survey and demarkation oi that part of 
the 100th meridian forming the boundary of Texas not covered by 
Messrs. Joues aud Brown's survey, and of the parallel of 30° 30' N. 
from its intersection with the 100th meridian to that of the 103d. The 
character of the determination and the method of running and mark- 
ing this portion of the boundary is reserved for a future report. This 
completes the field work of the boundary, except the small part of the 
103d meridian lying in the center of the staked plain and heretofore re- 
ported. I purpose running out and marking the arc that remains (about 
50') of this meridian on my return. 

Inclosed are copies in part of the astronomical observations, the N. 
west corner being established last season, for determining the parallel 
of 36° 30' and a rough sketch of this part of the line ; also observations 
with a sextant for determining the position in latitude of Fort Oobb. 

I shall, unless otherwise instructed, dispose of all the public prop- 
erty as soon after my arrival at Fort Smith as I may deem best for the 
interests of the government, and disband the commission. To accomplish 
this object I shall want about $5,000 (five thousand) in addition to 
what I have on hand, and what may come from the sale of the prop- 
erty. ' 
I am, sir, respectfully yours, &c., 

JOHN H. CLAEK,

UNITED STATES AND TEXAS BOUNDARY. 



No. 13. 

U. S. & Texas b'd'y, J. H. Clarke, com'r, Nov. 14, 1860. 
preliminary statements of last season's operations. 
Kec'd Nov. 16th, 1860. 




UNITED STATES AND TEXAS BOUNDARY. 291 

Washington, D. C, Nov. Uth, 1800. 
Hon. Jacob Thompson, 

/Secretary of the Interior : 

Sir : I herewith submit tlie following as a preliminary report of the 
operations of the Texas boundary survey during this season : 

Having reorganized the commission and so increased its force as to 
be independent of an escort, I proceeded from Fort Smith April 28th, 
by Forts Arbuckle & Cobb, to the 100th meridian where it intersects the 
Canadian Eiver. 1 arrived at this point June 8th, and commenced the 
survey by tracing the meridian northward to its intersection with the 
parallel 36° 30', forming the northeast corner of the boundary. 

While I was determining astronomically this corner, the surveying 
party was engaged in prolonging the 100th meridian up to the southern 
boundary of Kansas (37th parallel) with the view of connecting the 
longitudes of the two boundaries. The 100th meridian, determined & 
run as the eastern boundary of Texas, falls within 1,700 feet of the one 
fixed by me on the Kansas boundary in 1857. 

The northeast corner being thus fixed, & the northwest corner having 
been established the previous season, there remained only the operation 
of tracing & marking the parallel of 36° 30' between these two points to 
complete the northern line of the boundary. 

The tracing of the line westward was begun June 20th, and I had ad- 
vanced but a short distance with the work, when great dif&culty .was 
experienced for the want of water. The rains which may sometimes be 
looked for in this country to form water holes did not occur, and it was 
only by straining men and animals to their utmost capacity that I was 
enabled to carry the survey through. As an instance of the hardship & 
risk to which the commission was subjected to in this part of the work, 
from Union to Mustang Creek, a distance of 87 miles, had to be over- 
come without water. 

The parallel of 36° 30' was completed July 12th, when I set out for 
Fort Union to refit & reprovision the party with the object of going out 
on a staked plain and there complete the tracing and marking of the 
small arc of the 103d meridian remaining to be connected between the 
ends of this line, which had been run both from the south and the north 
last year. 

I ascended thebluff of the " staked plain " Aug.^lOth, but was forced to 
retrace my steps in two days for water. So completely destitute of water 
was this plain, that I could not get within 50 miles of the point I had 
reached last year. The customary rains had not fallen, and where last 
year I found large ponds or lakes, even of rain-water, were this year 
only dry beds cracked into deep fissures by the burning sun. 

I returned along the bed of the Canadian, and came again to the 
lOOth meridian Aug. 25th, and turning southward followed it to its 
intersection with the south or main branch of Eed Eiver. Thence I . 
marched eastward to Ft. Cobb, traveling along the northern edge of 
the Wishita Mountains over an unexplored section of country. 

Twenty thousand ($20,000) dollars, one-fourth of the whole appropria- 
tion, which contemplated only the field-work, yet remains unexpended. 
Thi^ surplus will be ample to complete the office-work, that is, the com- 
puting & tabulating of the astronomical observations, and the plotting 
and drawing of the maps. 

I have the honor to be, your ob't servant, 

JOHN H. CLAEK, 
Corner, cfcc, Tx's Wd^y Survey.

No. 14. 

Department of the Interior, 

July 27th, 1861. 

Sir : I have decided to transfer to your supervision and control the 
business connected with the U. S. and Texas boundary survey, and for 
your information transmit herewith a copy of a communication addressed 
to the department on the 24th instant by John H. Clarke, commissioner, 
&c., in charge of the work, showing the condition thereof at that date. 
Mr. Clark has been this day informed of the purj)ort of, this letter, 
and instructed to report to you hereafter in relation to all matters per- 
taining to the work in his charge. See copy of a letter to him of this 
date, herewith enclosed. 

You are requested to report your views to the dept. in relation to the 
expense necessary to be incurred in the completion of the office work, 
salaries, &c., incident to the survey. 

A copy of the correspondence of the department upon the subject of 
this survey will be prepared and sent to you as early as practicable. 
Very respectfully, your ob't servant, 

CALEB B. SMITH, 

Secretary. 
James M. Edmunds, Esqr., 

Commissioner of the General Land Office. 



Department of the Interior, 

July 27th, 1861. 
Sir: I have this day informed the Commissioner of the General Laud 
Office of my determination to transfer to his supervision and control all 
matters pertaining to the U. S. and Texas boundary survey. You will, 
therefore, report to that officer hereafter in relation to the work now in 
progress under your charge connected with said survey. 

Referring to your letter of the 24th inst., I will remark that the item 
for office rent, included in your estimate of expenses necessary to be in- 
curred in the completion of the work, can be omitted, as suitable accom- 
modations for an office can be furnished you by the Com'r of the Gen'l 
Land Office. 

Yery respectfullj^, your ob't servant, 

CALEB B. SMITH, 

Secretary. 
John H. Clark, Esq., 

Coni'r, &c., U. S. and Texas B^d^y, Wa'shington City. 



Department of the Interior, 

Wash., July 24, 1861. 
Hon. C. B. Smith, 

Secretary of the Interior : * 

Sir : By verbal request of Mr. Moses Kellj^, chief clerk, I make the 
subjoined statement, showing the condition of the office work of the U. 
S. and Texas boundary and survey at this date. 

Of the astronomical work, all the latitude observations have been com- 
puted and tabulated, and the observations for longitude recorded iu 



UNITED STATES AND TEXAS BOUNDARY. 293 

iform. As the results of the longitudinal determinations are not essen- 
I tial to the accuracy of the maps, except as checks, I do not i)ropose to 
prosecute this branch of the work further, and it may therefore be closed. 
j They can be computed hereafter, if desirable. 

! There are sixteen maps in all. One a general map, embracing all the 

'bouudary lines with much of the adjacent territory, and fifteen repre- 

, seiiting the line in detail. All of them are in an unfinished state, not 

comi)lete as to topography and lettering, and without any titles. These 

drawings must be executed to make the maps intelligible and answer 

the purposes for which they are intended, a delineation and record of 

the boundary. The general map will be ready for the engraver in a 

few days ; it will take two draughtsmen about three months to complete 

the rest. 

; The cost of finishing the work in the manner thus proposed will' be 

I about as follows : 

I ' ' 

[i Salaries of drauglitsmeu aud self $2, 000 

I Due Hesselbac for draughting 150 

Stationery and room rent 100 

Total... * 2,250 

. The engraving of the general map, if ordered, will cost from $1,500 

jto $3,500 according to the style and quality of the execution. 

j It is proper for me to state here, that, by agreement, I am under ob- 
ligations to furnish the Texas commission with plots and copies of the 
notes of a part of the survey. These have not yet been made, and the 
communication, which ceased on leaving the field last I^J^ovember, being 

[ impossible, I think it is no^r unnecessary to incur that exx)ense. . 

! I am, sir, respectfully, vours, 

JOHK H. CLAEK, 
Corner &G., Txh E'd^y Survey. 



Department of the Interior, 

Washington, August 2nd, 1861. 
Sir : Pursuant to the announcement in my letter to you of the 27th 
instant, I herewith transmit to you all the letters and papers and a tran- 
script of the correspondence of the department relative to the survey 
of the boundary line between the territories of the United States and 
the State of Texas.

(In pencil:) Copy of this report sent to Hon. J. J. Grroos, comm'r 
general land office of State of Texas, at Austin, March 10, 1877. 

General Land Office, 

SejJtemher 30th, 1861. 

Sir: In answer to your communication of the 19th inst., I reply as 
follows : 

1st. In execution of my instructions to survey and mark the bound- 
ary line between the Territories of the United States and the State of 
Texas, I proceeded, September, 1858, to San Antonio to confer with the 
Texas commissioner. It was there agreed between Mr. Scurry, the Texas 
commissioner, and myself to take the field as soon as the outfit could be 
made, and to begin the operations on the Eio Grande. My assistants, 
with the necessary instruments, having joined me, and the outfit being- 
completed, I left San Antonio the 12th of ISTovember, accompanied by 
the Texas commission, for the initial point, which was reached Janu- 
ary the 2d, 1859. The next day the work was commenced. 
' The performance of the astronomical work, upon which the boundary 
line is based, I undertook exclusively, the Texas commission taking a 
part in the tracing and demarcation of the line by furnishing half of 
the surveying force. The plan of survey adopted was to determine the 
line in latitude with a zenith telescope as often as it might be neces- 
sary to insure accuracy, and in longitude by triangulation and direct 
measurement from the initial point — the longitude of this point being 
found by transfer from Frontera, a well established station of the Mexi- 
can boundary Survey. From the meridian of each observatory a new 
tangent was turned, and being traced both east & west, the surveyor's 
line was seldom more than 30 miles without a check. 

A base line on which the whole suryey rests was selected near the in- 
itial point. It was 4,750 feet long, and was carefully and repeatedly 
measured with standard rods taken out for the purpose. The prepara- 



UNITED STATES AND TEXAS BOUNDARY. 297 

tion of the ground. for this base line and its measurement employed the 
surveying- party for ten days. The surveying party was then sent to 
Frontera to connect it with the point of beginning, which was iu the 
meantime fixed as to latitude by the astronomical party. To obtain 
tliis result a triangulation of the whole surrounding country was neces- 
sary, because of the meridian of Frontera being crossed by the many 
broken spurs of the Franklin Mountains. 

The initial point being established and marked by a stone monument 
bearing the necessary inscriptions, I commenced, January 26th, the sur- 
vey of the parallel or boundary line proper. After prolonging the line 
for 27 miles & putting up in that distance 6 monuments, I had to sus- 
pend operations from the Kio Grande Valley as a basis, it being too far 
to supply the parties with water. A reconnaissance showed that the 
next only available water, and that limited in supply, was to be had at 
the Hueco tanks. To this i3oint the surveying party, accompanied by 
an escort detailed from Fort Bliss, moved on at once and took upi the 
line. I remained near El Paso with the train till the 18th of February 
waiting the arrival of the permanent escort. 

When about leaving for the line I was notified by Mr. Scurry, the 
Texas comr., that he had resigned ; and as the waiting for a successor 
would have been attended with an indefinite delay, I went on and joined 
the surveying party at Alamo Spring. I intended to redetermine the 
parallel at this place, but finding it unsuited for such purpose, I made 
the 2d astronomical station at Crow Spring. The prolongation of the 
tangent was discontinued at Alamo Spring, and taken up from the re- 
determination at Crow Spring, was traced back and connected with the 
line as brought over from the initial point. This part of the 'i^arallel 
was marked by the following monuments : one on the Hueco Mountains, 
two near the first crossing of the Overland mail route, two between the 
first & second crossing, and two at the second crossing of this route. 

My observations at Crow Spring were completed by the 15th of March, 
when I left with the view of making my next station on the Pecos liiver ; 
but in turning the Guadalupe Mountains I found that they presented 
so rugged and so extensive a system of ranges, that the surveying party 
eould only, if at. all, at the expense of much labor and time, trace the 
line entirely across them. I therefore made another astronomical de- 
termination immediately east of the mountains and near Independence 
Spring. The surveying party joined me the 23d of March, and, as I 
anticipated, had succeeded in working only up to the middle of the 
mountain ranges. Leaving th,is i)arty to take up the line anew, and, 
after running it back, to continue its prolongation eastward, I moved 
from Independence Spring March 20 for the PeCos, where I again rede- 
termined the parallel. A number of moon culminations were taken at 
this station in addition to the usual latitude observations. The monu- 
ments erected between Crow Spring and the Pecos are one at the west 
base of the Guadalupe Mountains, one on the meridian of Independence 
Spring, two near Delaware Creek, one on the road leading up the Pecos, 
and one on its west bank. 

By the 15th of April the 32d parallel was run and marked from tlie Eio 
Grande to the Pecos, and in 3 days thereafter a flag was set on the 
"Llano Estacado" in the further prolongation of the line. By estab- 
lishing a depot of water it was continued out on the plain for 35 miles, 
and marked by 4 monuments, when it had again to be broken in con- 
sequence of the entire absence of water, & the presence of deep sand. 
The nearest water, after leaving the Pecos, was in the White Sand Hills, 
distant in a direct line 65 miles, and its discovery cost no little time, 



298 UNITED STATES AND TEXAS BOUNDARY. 

list, and exposure. By making a considerable detour to the south^ 
liowever, I managed to get sufficient supplies to these sand-hills, where 
I had the gratification to be able to redetermine the ]3arallel for the 5th 
& last time, and the 22d of May erected the monument, marking its 
intersection with the 103d meridian. 

Having completed the 32d parallel, I turned northward on the 103d 
meridian, using pack mules exclusively, as heavy sand precluded the 
possibility of taking wagons along. The meridian was traced uj) to the 
33d parallel, although every drop of water used had to be transported 
from the White Sand Hills. Finding no indications of water to the 
northward, and meeting with nothing but sand, I was forced to suspend 
the operations of the survey in this direction, and return to the main 
camp on the Pecos. This was reached the 31st of May. 

It is proper for me to state here that just before I left the Pecos for 
the White Sand Hills the Texas commission was withdrawn from the 
field by Mr. Scurry, the Texas com'r. The reasons which he assigned 
did not in my opinion justify an abandonment of the survey, and I there- 
fore kept on with the work. 

So much of the boundary line was thus run and marked during a se- 
vere winter over a country which, when not traversed by high and rugged 
mountains, presented only extended waterless stretches of sandy desert. 
The observations were often made in a temperature from 20 to 35° de- 
grees below the freezing point, and the operations of the surveying party 
arrested by storms so violent as to turn over wagons, lift the instrument 
from the tripod, and fill the atmosphere with dust and gravel. To ac- 
complish the survey of the 32d parallel, a distance of 211 miles, the note- 
books show that the party was compelled to travel 1,248 miles. This 
fact will give an idea of how much labor is necessary to effect a result 
in a country like that in which the Texas boundary line falls. 

After finding it impossible to trace the line further up through the 
plain, I returned to the Pecos with the object of tracing a meridian near 
that river, and of carrying out oifsets from it to the 103d meridian, and 
thus mark the boundary. I was ready to proceed the 1st of June, but 
was detained waiting for the escort till the 15th, when I went on and, 
reaching a i^oint about midway between the 33d & 34th jjarallels, fitted 
out a pack train, & with it started for the 103d meridian. This exam- 
ination showed that the river was much further from the 103d meridian 
than was anticipated, and that the intervening country, like the rest of 
the southern part of the staked plain, was formed almost entirely of sand 
and destitute of water. The plan of marking the 103d meridian by car- 
rying out offsets had therefore to be abandoned as impracticable. I then 
marched as rapidly as the nature of the country would permit for the 
northwest corner of the boundary, continuing a survey of the river as it 
was erroneously placed on the maps. 

The survey of the Pecos was made with sextant, compass, and viarae- 
rer, and connected with Capt. Whipple's route along the Canadian. In 
addition to the results obtained from these instruments, the bearings of 
all the prominent topographical points were taken with a large theodo- 
lite at each latitude station. Many of these points had already been 
fixed from the 32d parallel, and the bearings being read on them daily, 
the surveyor is enabled to lay down a map of the Pecos & oar route 
accurately, «& in direct connection with the boundary line. 

This route up the Pecos adds materially to the geographical knowl- 
edge of a region of country heretofore but little known, and demon- 
strates the x)racticability of a good wagon-road where it had been re- 
ported impossible to take a w^agon. It could be advantageously adopted 



UNITED STATES AND TEXAS BOUNDARY. 299 

as a line of communication between the frontier posts and settlements 
of Texas and New Mexico, for it is not only shorter, about 250 miles, 
than that by way of El Paso, but affords more wood, water, and grass. 
Such is the character and number of streams and springs putting into 
the Pecos from the west, that marches up from Delaware Creek could 
be so regulated as to enable the traveller to encamp every night near an 
abundance of wholesome water. 

I arrived at the first settlement on the Eio de Gallinas the 8th of 
July, and travelled directly on to Fort Union, leaving my escort behind. 
It joined me at Fort Union the 18th, but was not prepared to leave till 
the 27th of July, again delaying me 10 days. I then marched from Fort 
Union for Eabbit Ear Creek, where I commenced work for the estab- 
lishment of the northwest corner of the boundary. 

An observatory was put up at Eabbit Ear Creek and observations 
made for both latitude & longitude. The corner (the intersection^ of 
the parallel 36° 30' and the 103d meridian) was fixed as to latitude from 
these observations; but the surveying party were sent over to the 
Kansas boundary, and taking up the 103d meridian as then established, 
transferred it to its intersection with the parallel for the longitude. 

While at Eabbit Ear Creek a second Texas commission joined me, 
which, being unprepared to take any other part in the survey, threw 
up the mounds of earth marking the line; and I agreed to furnish the 
Texas commissioner with copies of field notes and plats. It was here that 
the only wild Indians met with during the whole expedition made their 
appearance. They marched up boldly in number, about 60, with the 
object, evidently, of inspiring fear by assuming a confident and defiant 
air, calling out in Spanish, as they approached, not to be afraid, as they 
would not hurt us. This tact failing them, they begged to be fed, say- 
ing they were Comanches and friends, and had come to eat and not to 
fight. When told that we could not feed such a band, they replied if 
you cannot feed our men feed our captains. The answer to such a reason- 
able proposition was that we had scarcely any provisions for ourselves ; 
they retorted it was very strange that in so many wagons we carried 
nothing to eat, and with this growl they took themselves off, not having 
been allowed in this " pow-wow " to come nearer than within rifle range 
of the camp and mules. That night and the next day they were hang- 
ing around camp, and twice attempted to stampede the cavallada. 

The fixing and marking of the corner being accomplished, the pro- 
longation of the 103d meridian was begun Aug. 23d. It was laid out 
from the meridian of the observatory, and checked as the line pro- 
gressd by observing the elongations of Polaris. From the corner to 
the Canadian Eiver the line passes over an undulating prairie, sandy 
and destitute of all forms of vegetation except grass: and although it 
was the rainy season there was a scarcity of water, and the bunting of 
it occux)ied much time. 

The meridian was traced with a large theodolite, and tbe distances, 
besides the direct measurements, made out from angles on the peaks of 
the mountains, and both checked as often as practicable with latitude 
observations. Fording the Canadian, and overcoming the broken coun- 
try about it, the Llano Estacado, marked by high and precipitous bluffs, 
was ascended near the 35th parallel, and the line continued and marked 
as far down as the 34th parallel. Here a belt of sand hills, traversing 
the plain nearly east and west, put a stop to the further progress of the 
train. The occurrence of this sand, together with the lateness of the 
season, compelled me to suspend farther operations this year and go into 



300 UNITED STATES AND TEXAS BOUND AEY. 

winter quarters, the Texas commission and the escort having already 
left the field. 

Besides the monument marking the corner, 9 were erected before 
reaching the Canadian, 2 on the Canadian, 3 between it and Oapt. 
Wiiipple's route, 2 on this road, one on the blutfs of the plain, and 6 on 
the plain. The 103d meridian being thus traced, and marked to the 
o4th parallel from the north and to the 33d parallel from the south, it 
mnj, for all practical purposes, be considered as completed. 

I ascended the plain with the determination of carrying the line at 
least far enough to ascertain if it struck Eed Eiver. In latitude 34° 30' 
two dry arroyos occur draining eastward, which are without doubt the 
first breaks of Eed Eiver, and which prove its head to be east and not 
west of the 103d meridian, as was supposed. Had I not been forced 
to quit the line on the south from physical causes, go up the Pecos and 
double my track again back on the 103d meridian, and to start in time 
to travel 600 miles for winter quarters, I could in one year have com- 
pleted all that part of the boundary covered by my instructions, in 
spite of the moral obstacles inseparable, from an exx)edition governed 
by three heads, as this was. 

Against all obstacles, however, physical & moral, the amount and 
quality of the work will compare favorably with what is & has been 
done in the same time, on similar surveys, as will be seen by refer- 
erence to the field notes. They show more than 3,000 astronomical ob- 
servations, & the survey of about 850 miles, 450 of which is triangu- 
lated on the boundary line proper. I took Capt. Whipple's road Oct. 
1st, for Ft. Smith, where I arrived early in November, and cut off all 
unnecessary expenses by a reduction of the commission, retaining only 
such officers and men as could be profitably employed during winter. 
By this reduction I was able to resume the field work and complete the 
survey without an additional appropriation. 

OPERATIONS IN 18C0. 

Having reorganized the commission and so increased its force as to 
be independent of an escort, I proceeded from Fort Smith, Ark., Ai^ril 
2S, 1860, by Forts Arbuckle and Cobb, to where the 100th meridian 
crosses the Canadian Eiver and there commenced work. 

That part of the 100th meridian lying between the main branch of 
Eed Eiver & the southern boundary of the Cherokee country had 
been determined, run, and marked by Messrs. Jones & Brown in 1859 
under the direction of the Indian Bureau, as constituting the boundary 
between Texas and a part of the Indian Territory. So much of the 
boundary line as was thus established, Hon. Jacob Thompson, then Sec- 
retary of the Interior, directed me to adopt, and in pursuance of this in- 
struction I simply retraced the meridian up to where the work of Messrs. 
Jones & Brown ended. Thence I prolonged it up to its intersection 
with the parallel 36° 30'. While observing for the determination of 
this parallel in order to establish the northeast corner of the State of 
Texas, the surveying party continued the meridian up to the southern 
boundary of Kansas, the 37tho parallel, and connected it with the 
longitude of that boundary. The result shows that the 100th meridian 
as fixed by me on the survey of the southern boundary of Kansas in 
1857, falls about 1,700 ft. west of that, forming the boundary line be- 
tween Texas and the Indian Territory. 

The northeast corner being thus established & marked, and the! 
northwest corner having been fixed the previous season, there remainedi 



UNITED STATES AND TEXAS BOUNDARY. 301 

only the operation of tracing & marking tlie parallel of 36^* 30' be- 
tween these two points to finish the northern line of Texas. The tracing 
of this line westward was begnn Jnne 20th, and I had advanced but a 
short distance when great dilficnlty was experienced for the want of 
water. The riiins which may sometimes be looked for in this region to 
form water holes did not occur this season, and it was only by straining 
men and animals to their utmost capacity that I was able to carry the 
survey through. As an instance of the hardship and risk to which the 
commission was exposed to in this part of the work, from Union to 
Mustang Creek, a distance of 87 miles, had to be overcome without 
water. The parallel was redetermined at Skull Creek to check the pro- 
longation of the tangent which was run out from the corner. A new 
tangent was taken from this redetermination and continued till it be- 
came necessary to leave it & strike to the north fork of the Canadian 
for water. It being impossible, in consequence of the absence of this in- 
dispensable element, to make another determination of the parallel of 36'^ 
30', I marched to the northwest corner, and thence run the line back 
to the last monument marking the boundary as brought over from the 
east. 

The northern boundary being thus finished, I set out July 12 for Fort 
Union to refit & reprovision the party with the object of going out on 
the staked plain and there complete the tracing & marking of the small 
arc of the 103d meridian remaining to be connected between the ends of 
this line, which had been run from the south &from the north as hereto- 
fore reported. I reached & ascended the bluft' of the staked plain 
Aug. 10th, but was forced to retrace my steps in two days for water. 
So entirely dried up was the plain that I could not get within 40 miles 
of the point I had attained the year before. The customary rains had 
not fallen, and where the season before I found large ponds of rain 
water were now only dry depressions of the prairie cracked into deep 
fissures by the burning sun. I returned along the bed of the Canadian 
and came again to the 100th meridian Aug. 25, and turning southward 
retraced it to its intersection with the main branch of Eed Eiver. 
Thence I marched eastward to Fort Cobb, along the northern edge of 
the Wishita Mountains, over a region of country for the most part un- 
explored. 

I append here a list of the monument, with a brief description. 

A. They were not put up at regular intervals, as will be seen by ref- 
erence to the maps on which they are represented, but on prominent 
points, roads, and where there was a possibility of the location of land 
or other question of jurisdiction. They were made of stone or earth, and 
show the position in latitude or longitude by inscriptions, as also the 
initial letters of the territories separated thereby, in most cases the 
dates too were added. There iuscriiJtions were cut in on the stone or 
wood. B. 

MONUMENTS ON 32d PARALLEL. 

1. Initial point, a pyramid of stone 8 feet high, whitewashed, with 
inscriptions on all the sides. It stands 600 feet from the bank of the 
river, and between them lies the road from El Paso to Fort Fillmore. 

2. On the first ridge of sand, built of stone around a stick of timber. 

3. On the first plateau, of a stick of timber ; a cotton-wood tree barked. 

4. On the first spur of the Franklin Mountains cut by the line, is of 
stone, & whitewashed six feet high. All four of these monuments can 
be seen from the road along the valley. 

5. Directly east of the Franklin Mountain, and on the road leading 



302 UNITED STATES AND TEXAS BOUNDARY. 

from El Paso to the salt lakes. It is a large mound of earth, capped 
with a slab of stone bearing the inscriptions. 

6. On the open prairie extending from the Franklin to Hueco Mount- 
ains. It is a mound of earth. 

7. A mound of earth on the road leading from Hueco tanks to the 
Mesilla Valley. 

8. Of earth on the ridge immediately north of the Hueco tanks. 

9. Is built of stone in a caiion of the Hueco Mountain. 

10. On the easternmost hill of the Hueco Mountain system ; of stone. 
11 & 12, One on each side of the mail route ; one of earth, the other 

made of stone. 

13. Is on a ridge of the Cornudas Mountains, and of stone. 

11. Also of stone on the table land lying east of the mts. 
15. This is on the same table land, & similar to the above. 

16 & 17. These are near to and on each side of the mail route where 
the line crosses it the second time. They can be seen from Crow SiJring; 
are pyramids of adobe built around stakes bearing the necessary in- 
scriptions. 

18. Is on a swell of ground just at the base of the first ridge, west of 
the Guadalupe Mountain system. It is of stone whitened, and is visible 
from the mail route or road about Crow Spring. 

19. Is of stone on the top of Guadaloupe Mt. 

20. Is at the east base of the mountain and due north of Independ- 
ence Spring. It is of stone. 

21. At Soda Creek, where the parallel crosses it, and is of stone. 

22 &.23. Are mounds of earth, within seeing distance of each other 
on opposite sides of Delaware Creek. These monuments in pairs were 
put up with the object of showing the direction of the boundary. 

24. Of earth, capped with a block of stone having the inscriptions, on 
the east side of the road leading uj) the Pecos. 

25. On the bluff near the west bank of the Pecos ; made of stone and 
gravel. 

26. Is on the Llano Estacado near Pope's well ; of stone with a large 
stick of timber in the centre. ^ 

27. A mound of earth at supply camp on the plain. Has a large sticki 
of timber in the centre. 

28. Is of earth on the highest ridge of the plain between supply camp; 
and the White Sand Hills. The soil here is formed almost entirely of 
sand. A flag-staff was left in this mound. 

29. Is near some bluffs in sandy soil ; of earth. 

30. Near some natural mounds in a depression of the prairie ; the soil 
of which this monument is made is rather firm. 

31. Is on the trail of the commission to the White Sand Hills, where 
there is a depression of firm ground surrounded on all sides by hills of 
sand. It is a mound of earth which is firm enough, probably, to resist 
the action of the wind. 

32. At the intersection of the 32d parallel and the 103d meridian. This 
is a mound of very sandy soil ; it has a bottle buried in it which contains 
the latitude & longitude of the point, a list of the names of the members 
of .the commission, and the date of its erection. 

MONUMENTS ON 103d MERIDIAN. 

1. This is a mound of tolerably firm soil on the road leading to & from 
the water in the White Sand Hills. It is thrown up around a stick oi 
timber, on which is inscribed the markings necessary to indie ate the line. 



UNITED STATES AND TEXAS BOUNDARY. 303 

2. Is a mound of eartli & near some slight bluffs. 
.'>. This is similar to [N'o. 2, except that a board, instead of a stake, con- 
tains the inscriptions. 

4. Is a mound just on the northern edge of a great sand belt. It is 
built of firm soil around a flag-staff. 

5. As all the monuments on the plain, with a single exception, ISTo. 5 
is also a mound of earth. It is on a slight roll or swell of the plain & 
near a large rain-water pond. 

6. This mound is on a flat plain of the prairie and has nothing to 
mark it ; it can, however, be seen at a great distance. 

7. Is placed near the main break of Eed Uiver, on the northern side. 
j 8. To the north of the north break of Eed Kiver stands I^o. 8, The 
plain here is as level as a table. 

9. The only one of stone on the Llano; it is near the bluffs, and can 
ibe seen much better from the valley than from up on the plain. All the 
monuments on the plain north of the great sand belt will remain con- 
spicuous for many years if not interfered with ; the soil of which they 
they are made is very close & tenacious. 

10 and 11. These are earthern mounds, erected on each side of the 
Albuquerque & Fort Smith road, and are close enough to show the di- 
rection of the boundary across the roads. 

V2. This mound is a little less than a mile north of the road, from.' 
which it can be seen. 

13. Is a mound, and south of the Caiiada de Truxillo but a short dis- 
tance. 

11. Monument 11 is on a ridge directly north of this creek. The soil 
is a little sandy here. 

15. A mound of earth, near the edge of a red sandstone bliiif, which 
forms the southern bank of the Canadian. 

16. This is of stone; in sight from No. 15 and on the north bank of 
the river. The angle at which the line crosses the river is shown b^^ 
these two monuments. 

17. Is on the first ridge, which is somewhat sandy, north of the river 
and made of earth. 

18. On an Indian trail leading east & west; stone. 

19. Earthen mound; on a ridge between two branches of Flag Creek. 

20. A mound of rather loose soil in Sand Valley. There is much sand 
along the line marked by this & the following 4 mounds. 

21. Stands on the south bank of the Maj. Long Creek and on a firm 
gravelly knoll. 

22. Mound of light soil on a sandy flat. 

23. Is north of some large sand-hills. The soil is loose and sandy & 
liable to drift. 

24. Of light soil, but not sandy; will resist the action of the wind. 

25. This mound is of firm «& close soil, & is in sight from the corner 
monument. 

26. The corner monument— the intersection of the 103d meridian with 
the parallel 36° 30'. It is an earthen mound, larger than most of the 
others ; and there is in sight of it, besides monument No. 25, No. 1 on the 
jparallel ; so that there are three monuments in sight from the apex mark- 
ling this angle of the boundary.

MONUMENTS ON PAEALLEL 36^30' 



1. This is near the corner monument, & earthen, as already stated. It 
will be lasting, as the soil is firm. 



304 UNITED STATES AND TEXAS BOUNDARY. 

2. The prairie is smoother where No. 2 is put than it is about the cor- 
ner. In all other respects ^o. 2 is similar to No. 1. 

3. On a ridge near the head of Mustang Creek. A mound ; the soil 
firm. 

4. Also a mound, three miles eastward of the last mentioned ; in sandy- 
soil. 

5. On meridian 102° 15' ; is in sand soil, too, but not of such character 
as to be swept away by the wind. 

6. The boundary line crosses one bend of the North Fork of the Cana- 
dian, called here the Rabbit Ear Creek. At the west crossing of this 
bend a stone monument was erected, near a bluft' of the river bed (which 
has no water here) southward. 

7. At the east crossing of the bend on the west bluft'is the 7th monu-i 
ment; of stone. This bend scarcely or never has any water. 

8. A mound of firm soil on the level plain, 

9. Is on the west bank of Union Creek ; built of firm & hard eartheii' 
soil. 

10. West bank of Skull Creek. Of material similar to the last, except 
that the stake is much larger than usual. There was an astr. station 
near here. 

11. East bluff of Skull Creek. Similar and in sight from No. 10 on^ 
the other side. 

12. On the open plain 5 of firm soil. 

13. On the smooth open plain where the trail leads off to the north. 
It is a mound of earth. 

14. Is on a flat ascending westward, and near Trout Creek. It is of 
firm soil. This point brings us fully into the buffalo region. The range, 
of this animal has a very important bearing on the monuments, for 
wherever it occurs most of the mounds will in a season or two disappear. 

15. The northeast corner monument at the intersection of the parallel 
30° 30' & the 100th meridian. This is a mound of earth, and falls in a; 
drain of a ridge, but not in a position that is likely to be washed away. 

MONUMENTS ON THE IOOtH MERIDIAN. 

1. On the north bank of Pond Creek. It is built of firm soil, and thei 
stake in the centre is a large barked cottonwood tree. 

2. Is on a trail made by Maj. Sedgwick and his command in 1860^1 
very near the north bank of Middle River. The soil is just here some| 
what sandy, but not light enough to drift. 

3. On Commission Creek, built of stone. 
Southward from this last monument, beginning at the southern b'd'f 

line of the Cherokee country, mounds of earth are thrown up for ever^: 
mile to the main branch of Red River. In retracing this part of thei 
boundary line 1 found that some of these monuments, falling in hollows, 
had been washed away, and many destroyed by the buffalo. The old] 
bulls tear them up with their horns, and but few mounds or hillocks ol 
any kind can be seen within their range that do not bear evidence of 
the wallowing of their shaggy heads and necks. All the creeks, bluffsi' 
plains, & ridges, & mountains referred to in the foregoing descriptionlj 
of the monuments are laid down & named on the detail maps. 

These artificial monuments may be put up with great care of the mostj 
lasting material, yet the chances are that all traces of many of them wil| 
be swept away in a few seasons ; for besides their destruction within, 
the buffalo range, the wild Indians will certainly tear down all the;^: 
meet with, particularly those made of stone, which will not give them s(

jauch trouble as the earthen mounds. The maps with the note-books 
|,re the only real and lasting record of the boundary. The line runs 
hrough a country full of striking and prominent topographical features, 
Irhich can be easily identified ; and being referred to in the note-books 
jind laid down on the maps in latitude & longitude, they can be taken 
,s starting points from which, with bearings & distances, the boundary 
ine may be found & retraced at most any place in any time without 
eference to the monuments at all. Such features are named as follows : 
2d parall. Franklin Mountains, Organ Mountains, Hueco Caiion & 
:anks. Sierra Alta, Alamo Spring & Mountains, Cornudas Tanks & 
lountains, Crow Spring, Guadalupe Mountains (its southern peak par- 
icularly), Independence Spring, head of Delaware Creek, crossing of 
*ecos & its junction with Delaware Creek, Pope's Wells, small bluffs

laraliel & 103d meridian). 103^ meridian. Small bluffs, sand belt, lines 
f rain-water ponds, breaks of Eed Eiver, bluffs of staked plain,* cross- 
ig of Canadian, tips of of mountains on the west, chalky bluffs, sand 
idge, Eabbit Ear Mountain, near northwest corner. Parallel 36° 30'. 
lead of Mustang Creek, crossings of a bend of the north fork of Cana- 
ian, head of Union Creek, crossing of Skull Creek, Kiowa camp ground,

rounds near Eed Eiver (main branch). 

2. The "platting" or projection was finished as long ago as the 1st of 
anuary, it being done before the drawing & lettering were commenced, 
he force engaged at present are J. H. Clark, at a salary of $3,500 per 
Q., without any allowances of any kind in the field or out of it; H.

le commission. The astronomy is closed up, and the detail maps I 
ill endeavor to have completed some time in ISTovember next.

Qd the adjoining country, and which it is presumed will fully supply 
jll the purposes of a sketch plat and diagram.

No. 17. 

Department of the Interior, 

Genl. Land Office, Oct. UtJi, 1861. 
Sir : You have entirely misconstrued wliat I said in reference to the 
permanency of the monuments. I could not have stated that I found 
on retracing the line that monuments built by me had been " obliterated 
by natural and other causes," for I never retraced any part of thelme 1 
had once determined, surveyed, and marked. I do not therefore know 
anything of the condition, of the various monuments put up by me; hul 
as they were of large dimensions and of the most substantial material 
possible, I believe they will endure the wear of time, wild animals, anc 
wild Indians as well as any monuments ever constructed in the Unite(l 
States to mark boundary hues. What I stated on this point has refer 
ence only to that part of the 100th meridian surveyed and marked u 

1859 under the direction of the Indian Bureau, and which I retraced ii 

1860 for the purpose of identifying it. . ^ . ^ 
I repeat that under no circumstances could these landmarks be madi 

more substantial or lasting. That some of them will not remain on thi 
" earth's surface to a distant future" is quite probable; not from tb 
fault of construction or material, however, but from the accident of thei 
position and surroundings. To guard against this very contingency 
their accidental or wiUful destruction, I had the boundary line coii 
stantly referred by triangulation to prominent physical objects whic] 
can be easily identified, and which will never in all human probabiiit; 
be " obhterated by natural and other causes." 

What I endeavored to convey to you in my report bearing on the pei 
manency of the ihonuments was that even in the event of their destriK 
tion, the line could be re-established by a common surveyor without 
repetition of the scientific and expensive operations employed in detei 
mining the parallels and meridians constituting the boundary. 

That the survey has been "long in progress" cannot be asserted wit 
justice, if any regard be had for its great extent and character; and tli 
imputation of unnecessarily protracting it cannot be sustained, nc 
would it be made by any one having a correct knowledge of the km 
and amount of work I have accomplished both in the field and ofdce. 
This survey has been a work of the first magnitude. To fix the bouii( 
ary line 800 miles in length, it was necessary, because of physical obsti 
cles, to make more than 1,400 miles of survey checked by nearly 4,0( 
astronomical observations, besides many miles of reconnaissance survey 
The office work in addition to the computation of all the astronomici 
observations consists of the computation of the triangulation, the plo 
ting and drawing of 15 details map delineating the topography alou 
the boundary line in the highest style of the art, and a general nn 
showing the boundary in connection with all the adjacent territorie 
This map contains besides the topography a list of many importa? 
points determined bv me in latitude and longitude ; and is the only cc 
rect representation of all that great stretch of country lying betwe- 
the meridians 98 & 107 and the parallels 32 & 37, from the timberj 
regions of Texas and the Indian Territory across the plains to the Eoc| 
Mountains, and from the southern limits of the great staked plain nort 
ward to the Arkansas. 

It is true as you state that the sum of 872,550-1^0^ lias been expemlj 
on the field and office work of this difficult & extensive survey ; but ^ 
this statement I do not mean the fact shall be put out of view that I ha 
completed the field work and nearly all the office work, and yet ha 
unexpended about $8,000 of the appropriation which w^s designed 



UNITED STATES AND TEXAS BOUNDARY. 307 

' cover the expenses of tlie field work only. I make no reference to the 
$10,000 which was taken by the department and expended for purposes 
foreign to the survey for which it was appropriated. 

If you will compare the expenditure of money and time on this survey 
with the amount of work done and the geographical and other knowl- 
edge famished— its cost with its results— you will find that, though exe- 
cuted in a scientific & artistic manner, it has been done at an expense 
to the government per mile that is usually paid for rough and primitive 
compass surveys. 

I have discharged the duty that was entrusted to me on a scale of 
economy unprecedented in the history of similar expeditions ; and I 
invite you to draw a parallel between the expedition which has been 
thus executed under my direction and any one similar in organization 
and object, not only as to number of persons employed, but as to amount 
of salaries, style of outfit, and every other outlay pertaining to both 
field and office work. 

You state that you are anxious to close my work, and that having a 
large clerical force applicable to my assistance, you would be glad if 
they could be made to expedite the completion of my business by dimin- 
ishing my force. To this I can only reply that I have no use whatever 
for any clerical force. There are only three persons now employed, and 
these as topographers. They, were in the field as my assistants, and 
being familiar with the details of the survey, are alone competent to 
properly execute the topography that remains to be done. 

In compliance with your wish that the work be closed by the middle 
of next month, it shall be prosecuted with that end in view, and be put 
in as complete a form as the time will permit, though I deeply regret 
that the results of a survey prosecuted with so much labor and care 
should be so hurriedly, and I fear so unprofitably, disposed of. 
I remain, respectfully, yours,

Sir : In sending the invoice my only purpose was to inform you as to 
what constituted the archives of the commission. The astronomical 
work, as I reported, is finished and is ready to be turned over. The geo- 
detic .part of the survey is also all complete, except the maps. 

I have so far progressed with the maps, however, as to be able to 
state that I can get them in a condition to show an intelligible delinea- 
tion of the boundary line in about six weeks — say some day during the 
last week of February next, when they also will be ready for transfer.

Department of the Interior, H '

Hon. C. B. Smith, 

Secretary of the Interior : '■ 

Sir : I have received a copy of your communication of Jan. 16th inst. 
to Mr. Edmunds, Land Comr., directing that the work of the Texas 
boundary survey be terminated at once without reference to its unfinished 
condition. It is not my purpose, in thus addressing you, to obtain a re- 
versal of your decision, but simply, in justice to my feelings and my self- 
respect, to repel the accusation of Mr. Edmunds, upon which it appears 
your judgment is based. 

Mr. Edmunds says that the balance on hand, Dec. 31st, 1861, is $4,800, 
and that the time I have fixed to complete & transfer the work "wiU 
probably absorb the whole appropriation." This statement is as erro- 
neous as the implication is unjust. The balance unexpended of the appro- 
priation of $80,000, Dec. 31, 1861, is $7,017, and not $4,800 as stated by 
Mr. Edmunds, and the time fixed by me would have absorbed only about 
$1,000. Deducting this sum from the amount on hand Dec. 31, '61, I 
would have completed the office as well as the field work, and returned 
to the department a surplus of about $6,000, besides the property on 
hand, out of the appropriation which was designed to cover the expenses 
of the field work only. This inaccuracy is in accord with the course of 
the Land Office towards my work, which it has never given itself the 
trouble to examine, and cannot therefore appreciate its scientific merit 
or practical bearing. 

I was exceedingly anxious to finish a work I had prosecuted with so 
much labor and with such success ; and in transferring it thus, must re- 
spectfully protest against being held responsible for its unfinished and 
unavailable condition. 

I remain, respectfully, yours, 

JOHN H. CLAEK,
